Taylor Swift's 'I Knew It, I Knew You' has debuted at No. 1 on Billboard's Top Movie Songs chart for June 2026, ending a three-month run of dominance by Michael Jackson's catalogue from the biopic 'Michael.' The song, released on June 5, two weeks ahead of the Toy Story 5 premiere on June 19, plays during the film's credits as the first song audiences hear as the roll begins Billboard.

The numbers behind the chart-topping placement are substantial. According to Luminate, the data firm that tracks U.S. music consumption, 'I Knew It, I Knew You' earned 73 million official on-demand streams and sold 89,000 downloads in June alone. The track also hit the Billboard Hot 100 — the flagship singles chart — at No. 1 immediately, holding the position for two consecutive weeks dated June 20 and June 27 Billboard.

Billboard categorises the song as country, a genre Swift revisited well before it became a talking point in 2026. The collaboration is branded 'Disney-Pixar x Taylor Swift' on her official website, which promotes it as the featured original song from Toy Story 5. A lyric video was released through the DisneyMusicVEVO YouTube channel, with Disney Music promoting it across social platforms Billboard; taylorswift.com.

Swift's No. 1 displaced a Michael Jackson stronghold. Songs from the biopic 'Michael,' which premiered on April 24, 2026, had occupied the Top Movie Songs chart for three consecutive months. 'Billie Jean,' which led the chart in May, dropped to No. 2 in June with 71.1 million streams and 7,000 downloads — a streaming total just shy of Swift's but with a fraction of the download sales. Five more Jackson tracks held positions 3 through 7 Billboard.

The rest of the June chart drew from other major film releases. The Chemical Brothers' 'Go,' from the film 'Apex,' ranked No. 8 with 10.6 million streams and 7,000 downloads. Sienna Spiro's 'Material Lover,' from 'The Devil Wears Prada 2,' placed No. 10 with 13.8 million streams and 3,000 downloads Billboard.

The Top Movie Songs chart is powered by Tunefind, a Songtradr company that tracks song placements across film and television. Rankings blend Tunefind's song-and-film data with sales and streaming figures tracked by Luminate — meaning chart position reflects not just how much a song was played, but how strongly its connection to a film drove listener activity Billboard.

For a song tied to an animated franchise about toys, the chart's country classification and download numbers — 89,000 in a single month, when download sales across the industry have been declining for years — point to an audience treating it as more than a soundtrack curio.
